Emails deleted
Everything is gone... all gone... all the love letters from my to-be-husband... emails from my now-deceased mother... a decade or more of my life... deleted.
And no warning, no restore options... just purged. Why do this with no notice?
I stayed loyal through all these years, even when everyone said Gmail was infinitely better. I hated the inbox makeover, but still stuck with Yahoo.
Now this? It's the last straw.
Google may be an evil monopoly, but Yahoo deserves to go out of business for this.

Hi there! Here’s an article regarding finding missing emails: https://help.yahoo.com/kb/mail-for-desktop/sln4538.html
You can request a mail restore here: https://help.yahoo.com/kb/SLN2552.html Once the restore is complete you would need to check your Trash folder for the recovered messages.
Hope this helps!
